MASK FOR MAKING PHOTOGRAIHIC PRINTS.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed March 21, 1917. Serial No. 156,435.

To all whom, it may concern:

Be it known that I, CHARLES W. WILSON, a citizen of the United States,and resident of York, Pennsylvania, have invented certain new and usefulImprovements in Masks for Making Photographic Prints,- of which thefollowing is a specification.

My invention consists of a mask for defining the field which will beprinted upon a sensitized hotographic paper and for definin a bor erportion surrounding the said fie d having thereon border marks or lineswhich will not only act as guides in trimming the sheets but will enablethe customer to choose any one of a number of borders which may bepreserved inthe trimming, thus rendering it possible to cater to thevarious tastes of customers.

In carrying out my invention I provide the mask with means wherebyguiding marks may be made on the prints beyond the. margins surroundingthe field, which marks Wlll enable the photographer to trim the print inany one of a number of ways to suit the taste of the customer, the marksbeing disposed in a novel relation so that although they act asguidesfor trimming they are so located as to render possible the choiceby the customers of different borders.

I am aware that masks have been disclosed prior to my invention forexposing a i as in Letters Patent of the United definite size of fieldto be printed on the sensitized paper and to print or provide in theprinting process guiding marks adjacent the corners ofthe field fortrimming States, Nos. 1,060,618, and 1,061,727.

In the drawings;

Figure 1 is a view of the mask.

Fig. 2 is a view of a print made from the mask, this print not beingtrimmed.

Fig. 3 represents the print trimmed according to one of the designs fromwhich a choice may be made.

Figs. 4 to 7 represent the print but with different styles of borders,all of which may be made by following either one of the several guidesor indicating lines or marks made on the print through the mask when theprint is being made from the negative in the ordinary way.

Fig. 8 shows the corner of a print provided with ornamental borderlines.

In carrying out the invention I may use as the material of the maskcelluloid or glass. It is provided with a portion 1 transparent or openfor the passage of the light and having surrounding this open ortransparent field portion a light resisting portion, indicated at 2.Surrounding the portion 1 and spaced apart-therefrom by an interveninglight resisting section 3 of the light resisting body 2 I provide aborder marking 4, which may consist of a continuous line, as shown, orthis marking may be of any suitable design, character, such as finescrollwork or the like. This border marking will permit the passage ofthe light and produce a border on'the print when this is developed.

I also provide a second border markin 5 separated from the first by anintervening portion 6 of the light resisting body and this second bordermarking may -be a continuous line like that first described, or it alsomay be of any desired design, such as scrool-work or a curved line orlines.

Any desired number of these border markings may be employed but I havefound that two such markings will answer 'all requirements.

In the light resisting body or portion 2 I also provide guide markingsshown at 7. These being out beyond the border markings and separatedtherefrom by intervening opaque or light resisting parts of the lightresisting portion 2, these intervening parts being indicated at 8.These' guide markings will be printed on the paper when the \mask isapplied thereto between the negative and the sensitized surface of thepaper and they will serve for guidance in the trimming of the print. I

It will be noted that these markings are in line with the bordermarkings, though separated or spaced therefrom and out beyond them, eachmarking being in line with one of the border lines or markings and thereare twice as many guide markings at each corner as there are bordermarkings surroundin the transparent. fields 1. The border mar iings maybe continuous to en tend entirely around the open field 1 or they mayextend only part way around, as the taste of the photographer orcustomers may dictate.

The print resulting from the use of this mask may be trimmed to presentany one of a plurality or series of border efiects.

Fig. 2 illustrates the print resulting from the use of the mask beforeany trimming is done.

Fig. 3 illustrates one form of trim in which the print is cut away inline with the inner ends ofthe guide markings. This will leave a narrowmargin 9 beyond the second or outer border line and between it and theed e of the print or sheet.

if. a shows another style of print resulting rom trimmin alon line butleaving sa1d bor er line on the paper at the extreme margin of theprint.

Fig. 5 illustrates another method of trimming b which awhite margin isleft between t e inner border line and the edge of the paper, the outerborder line having been trimmed away along its inner edge.

Fig. 6 illustrates another form of trimmin in which the inner borderline is left on t e print while the margin outside of this border lineis trimmed away.

Fig. 7 illustrates a further style of print resulting from trimmingalongl the inner edge of the inner border hne so t at this will betrimmed away entirely leaving a white margin between the picture fieldand edgeof the paper. I

By these several forms of trims the photographer can suit the tastes of,various customers. The border lines together with the ide markings willenable the trimming to e done with ordinary shears or the usual form ofcutter may be employed, such as shown in the patents above referred to.

I may employ as the mask a plate of glass sheet material aS celluloidhaving the border and guide markings together with the opaque fieldvprovided thereon in any suitable way.

Instead of having the center 1 of transparent material an opening may beformed here and instead of making the border of transparent markingsparts may be cut out from the material of the mask to provide thisborder marking.

It will. be understood that instead of celluloid or glass the mask maybe made of any suitable material as paper.

What I claim is:

1. A photogra hic mask havin a central portion or fie d or the passage 0light surrounded by a light resisting portion and the outer border 7producing marks at the corners of an transparent border marks in saidlight resisting ortion with transparent guide marks a jacent the cornersand out be and the border markings and separated t erefrom by anintervening part of the light resistin portion of the mask,substantially as descri ed. 1

2. A photographic mask havin a central portion or fie d for the passage0 light surrounded by a light resisting portion and transparent bordermarkings in said resisting portion substantially continuous andsurrounding the field with transparent uide out beyond said border andseparated therefrom by an intervening part of the light resistingportion of the mask, substantially as described.

3. A photo raphic mask havin a central portion or fie d for the passage0 light surrounded by a light resisting portion and transparent bordermarks in said light resisting portion with transparent uide marksadjacent the corners and out eyond the border markings and separatedtherefrom by an intervening part of the light resistin portion of themask, said guiding marks being at right angles to each other at thecorners and in line respectivel with the adjacent border marks,substantlally as described.

4. A photo aphio mask havin a central portion or fie d for the passage0% light and a light resisting portion surrounding said field with aplurality of markings or borders for the passage of the light arran edin said light resisting portion and at dierent distances from t e fieldwith guide marks separated from and out beyond the border markings andadjacent the corners thereof, there being twice the number of such guidemarkings at the corners as border mark- I ings and said guide markingsbeing in line with the border markings respectively, substantially asdescribed.

In testimony whereof, I afiix m si nature.
